' specification of Letters mum. gu m n July so, was;

Application filed AprildQ, 1910. Serial No. 556,392.

' Allegheny and State of Pennsylvania, have invented a new and useful Improvement in.

C nilensers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,

forming part of this specification, in

which- Figure 1 is a sectional elevation of a barometric condenser embodying my invention, and Fig. 2 is a similar view of a portion of a modified condenser also embodying my invention.

My invention has relation to condensers, and is designed to provide the condensing chamber with a water reservoir of suflicien't capacity to keep the outgoing cooling water ofa nearly constant temperature, this reservoir providing means for taking care of fluctuations in the amount of steam passing through thecondenser and preventing overheating oi the cooling water.

' Referring first to Fig. 1, the numeral 2 designates the condensing chamber, having an inlet opening at 3 for connection with the usual water supply pipe, and an opening at at its upper end, for connection with the usual exhaust or vacuum pipe. 5 and 6 designate interior cones, cups, or bafiies, which are arranged to produce a spraying action of the water discharged into the chamber at the opening Any suitable arrangement of these battles may be used. The water entering at the opening 3 flows over the upper end of the upper cone or battle 5, thence downwardly into the cup below the top opening in the cone or batlie 5 and thence over the edges ofsaid cup into the cup of the lower battle 6. 7 designates the steam inlet pipe whichenters the lower portion of the condensing chamber 2, and 8 is the usual tail pipe. Placed in the condensing chamber, below the cup or battle 6, is a centrally arranged upwardly extending annular bafile 9,? which is separated from the outer wall of the chamber 2 by a water space 10 into which extends a depending annular batiie 11,, whose lower edge terminates a short distance above the lower edge of the bafie 9. The water flowing over the upper edge ofthe cup thus flows. down wardly into the space or chamber 10 outside of the bafiie 11 and thence upwardly between the bafile 11 and thet 'eentral bafie 9, and thence downwardly ov er the inturned edge 12 of the lower bafiiefand into the' lower chamber'Q. Another cup or baiiie 13 maybe placed below the inturned edge 12 of the battle 9. The space orchamber 10 is of a capacity such as will enableit to retain at all times a considerable body of water, this body being of suflicient volume to take care of the fluctuations in the action of the condenser without becoming unduly heated.

it will be understood the condenser is of the well known counter-current type in which the steam flows upwardly against the down flowing spray or shower of water.

7 In Fig. 2 I have shown my invention applied to a barometric condenser of the peculiar type of my Patent No. 926,486 of June 29, 1909, in which the steam inlet pipe 7 extends vertically upward through the bottom wall of the condensing chamber at one side of the tail pipe, its upper end 7 terminating within the condensing chamber. This form of the invention is otherwise the same as that shown in Fig. 1, except that l: have omitted the lower cup of the upper bathe-5.

As above stated, any suitable arrangement of baiiies may be provided within the upper portion of the condensing chamber for pro ducing the proper spray or shower of water, I

' my invention residing solely in. the provision within the condensing chamber of a geservoir of water, as described.

Whatl claim is:

A condenser of the countercurrent type, having a water inlet at its upper portion and a steam inlet at its lower portion, and at its intermediate portion having two concentric cylindrical baiiies,- the inner battle surrounding a steam and water passage and having a water overflow at its upper edge,

and the outer baiiie being separated from the inner baffle and from the wall of the condenser by water spaces, said outer baffle' extending above the upper edge of the inner baflle ajnd having a central opening, and

there being an opening below the lower edge upper end of the outer bafile; substantially as described. 10

" In testimony whereof, I have hereunto set my hand.
